“…Group differences on gait parameters were examined under different terrain and task conditions in 11 papers (all high quality): (i) overground walking on regular and irregular terrain (Gentle et al, 2016;Nieto et al, 2018); (ii) treadmill walking (Speedtsberg et al, 2018;Yam and Fong, 2018); (iii) overground walking with intermittent and occluded vision (Nieto et al, 2018); (iv) stair negotiation (Parr et al, 2020b); and (v) locomotor pointing and obstacle avoidance tasks (Schott et al, 2016;Wilmut and Barnett, 2017a,b;Parr et al, 2020a;Warlop et al, 2020b). The overall effect for all gait outcomes was moderate On clinical scales that assess the coordination of gait under different sensory conditions, studies showed that those with DCD have significantly poorer gait coordination than TDC peers (d = 1.57, 95% CI = [0.78, 2.37] on a functional index, and d = 1.06, 95% CI = [0.08, 2.04] on an ataxia index) (Mannini et al, 2017;Hsu et al, 2018).…”
